msloniewski a826aacac0 build/altera: Add possibility to turn off generation of .rbf file
For some FPGAs (e.g. MAX10) .rbf file cannot be generated.
Add possibility to turn off that feature for those chips.

software/libbase: memcpy: simple, arch-width agnostic implementation

Gabriel L. Somlo f88b85a31c software/libbase: memcpy: simple, arch-width agnostic implementation
Remove optimizations targeted specifically at rv32 architecture,
allowing memcpy to work on all word sizes.

Since this is "only" the BIOS, it is also arguably better to
optimize for size rather than performance, given that control
will be quickly handed over to some other program being loaded.

Gabriel L. Somlo 019fd94005 fixup: generated-verilog submodule for experimental Rocket support
FIXME: This patch uses https://github.com/gsomlo/rocket-litex-verilog,
however in the long term it would perhaps be better if enjoy-digital
hosted the generated-verilog repository.
Once that's in place, I'd be happy to re-spin (and squash) this patch
on top of its parent -- GLS

Gabriel L. Somlo 1a530cf27d soc/cores/cpu/rocket: Support for 64-bit RocketChip (experimental)
Simulate a Rocket-based 64-bit LiteX SoC with the following command:

  litex/tools/litex_sim.py [--with-sdram] --cpu-type=rocket

NOTE: Synthesizes to FPGA and passes timing at 50MHz on nexys4ddr
(with vivado) and ecp5versa (with yosys/trellis/nextpnr), but at
this time does not yet properly initialize physical on-board DRAM.
On ecp5versa, using '--with-ethernet', up to 97% of the available
TRELLIS_SLICE capacity is utilized.

Gabriel L. Somlo e90caa8683 tools/litex_sim: restore functionality of '--with-sdram' option
After LiteDRAM commit #50e1d478, an additional positional argument
('databits') is required by the PhySettings() constructor.

The value used here (32) will generate a 64MByte simulated SDRAM.

Sean Cross 014c950580 remote: usb: print "access denied" error
When we get an error with errno 13, it means that the user doesn't
have access to the USB device.  Rather than silently eating this
error and returning -1, print out a message to aid in debugging.

Sean Cross faf6554c89 remote: usb: use 0x43/0xc3 for packet header
The previous value -- 0xc0 -- is used by Windows all the time to query
special descriptors.  This was causing a conflict when using the USB
bridge on a Windows device.

Change the magic packet from "Vendor: Device" queries to "Vendor:
Other" by setting the bottom two bits.
